Bulimia nervosa

From Conservapedia

Bulimia nervosa is an eating disorder characterized by recurrent episodes of binge eating followed by compensatory behaviors, or "purging". Types of purging include self-induced vomiting, fasting, overexercising, or the abuse of laxatives, enemas, or diuretics. This disorder occurs among some who suffer from anorexia.[1]

Because suffers from bulimia tend to be an average weight, this disorder tends be more difficult to diagnose than other eating disorders.
